I have been doing some research about how to do verification automation on sent emails - but haven't really found anything that has worked thus far.
Here is what I need to test:
We have a customer portal where our customer service reps set a "Template" to be used for email and SMS communications. I am tasked with verifying that the email/SMS that is sent from us is received at our customers inbox with customer data and styling being the same.
Our team has internal API's that I can use to execute the JSON requests to send the communications. Personally I have attempted to test this with Selenium by logging into a gmail account and verifying the text that comes into the email, but it doesn't really check for the stylistic viewing of the email in the inbox. I haven't found any suitable SMS platform to see text messages. Any help on this issue would be appreciated.
Manual testing is not an option because we have 20 or so communication types and about 10 templates in each one. It takes a lot of time to test manually, so it really is a good candidate for automation with our small-er test team
